This thing WORKS!

I had been working in my attic on Saturdays for about two months off and on to get a floor down and shelves built. Every time I came out I was sick for a week with a sinus infection. I tried a simple dust mask but the result was laughable so I decided to get a more expensive one and this is it!
It fits perfectly and since using it I have not even had a sniffle or sneeze when I am done for the day. Working with eye protection takes some adjustment but the bottom line is is this thing works!
It was cheaper than I expected and it got here quicker than I expected.
An all-around great experience.
I wore it 22 hours a day!

I am extremely allergic to grasses and dander, because of this I had not visited my daughter and 4 grandchildren in the grassy state of Idaho for 4 years. I purchased two of these hepa masks, wore them 22 of 24 hours a day and had an extraordinary visit! I could not have done it without these hepa mask respirators!

My new mask makes the yard work pleasant. True. No more coughing and choking. I should have bought one years ago.
Customer Q & A
Q1: Are these suitable for a herbarium where fungal spores will be? A: They SHOULD help. I am relying solely on generalized data in terms of average fungal spore size. But, the average size ranges from just a few microns 2-5 to well over 100. More will likely be on the small side of this range, but with a HEPA mask rated to filter 99.97% of particles 0.3 microns or larger, you should be able to remove most of the spores in this range, that you may encounter. Of course, I cannot give very definitive answers since there are a lot of variables that will impact filtration performance including not only the size of the spores but also the type and concentration of the spores in the space where you are working, length of time you are working in that space, etc. For work in a herbarium though, a HEPA respirator, when properly fitted, should help to dramatically reduce exposure and most types of fungal spores. Hope that helps!
Q2: I own a small hobby farm, which includes raising pigs. Every time I do any work in the barn it takes 2 days to get rid of the effects of the dust and hay. Will this mask allow me to do work in the barn for hours at a time without my asthma flaring up, or what other option would you suggest?
A: Truthfully, something as simple as the 8210 dust mask should help. I might try this first before investing in a heavier duty mask. The 6291 should most certainly eliminate nearly all the dust you are breathing in right now, but I would progressively build up to that type of mask. You may find the inexpensive 8210 does the trick. If it doesn't though, any of the 3M HEPA masks will work well. the 6291, 8233 or 8293.
Q3: Hello, I had a few questions about this product, as I am very interested.
*Would his work well for filtering out chemical perfumes and fragrances?
*What materials are the product made of, aside from plastic? Such as the material of the HEPA filter itself?
Thank you
Sara
A: Not ideal, in terms of fragrance filtration. The mask itself is a non-latex rubber, and the HEPA filter is a cloth HEPA filter media material. There is some plastic used as well.
For better odor and fragrance filtration, opt for the Organic Vapor cartridges. The give up a little in terms of particle filtration but will provide much better filtration of perfumes, odors and vapors.

3M 6291 HEPA Mask
The 3M 6291 HEPA Mask is one my favorite face masks. Unlike disposable masks, the 6291 is durable and can be used repeatedly. I
have owned this mask for a several years, and have changed the
HEPA filter cartridges twice. I use this mask for just about everything from yard work to more heavy duty projects like
like replacing the grout in our shower. Depending on usage, you may have to replace the filters more often, so
this will vary depending on use. After several years of service, this my assessment of the 6291 respirator.
What I like about the 3M 6291 HEPA Mask
Offers HEPA quality filtration of oil and non-oil based particles
Versatile filtration ideal for a wide range of uses from pollen and mold particles while raking leaves to
filtering oil based particles you might encounter while staining or working with wood or fiberglass while renovating or
working on your home
Creates a very tight seal
It is durable and easy to clean after dirty projects - rinse respirator itself with warm water or with a mild detergent (filters NOT washable)
Fits very snugly with two straps and is fully adjustable
What I did not like about the 3M 6291 HEPA Mask
As with any tight sealing mask, in warm conditions it will make the area around my mouth sweat, so some
moisture will get trapped inside
In all, the 3M 6291 HEPA Mask is the best masks we offer. With NIOSH P100 filtration, this respirator is one of the most versatile available today.
It is completely sealed, non latex, HEPA grade, and you can replace the filters when necessary. If you, have allergies, do a lot of yard
work, work in a shop or in places where things toxic and non-toxic particles are a concern, I strongly suggest using this mask.
The filtration this mask provides also exceeds the CDC's recommended filtration level (N95) to help prevent the spread of the
influenza virus. Aside from it being a little warm with extended use or in warm conditions, there is very little not to like about this
durable HEPA respirator.
